The Worm-Wheels h are replaced by bevel gear-wheels O, which mesh with bevel gear- Wheels 19 on a shaft P, arranged parallel With the shaft N and journaled in hearings in the jonrnal-brackets M. This shaft P is driven by the sprocket-chain .90 from the motor,which chain engages a sprocket-Wheelp on the shaft P, as will be readily understood by reference to Figs. 4 and 5 of the drawings.

The vehicle is designed to be used principally on snow, and in operation the drivingdrums H are revolved, the flanges h sinking into the snow and propelling the vehicle in the manner of a screw-propeller. The surfaces of the driving-dru ms between the spiral flanges 'lheing smooth will slip easily on the snow and offer very little resistance to the motion either of the drums or the vehicle.

It will be seen that many modifications may be made in the details of construction of this device without departing from the spirit of the invention.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is

1. In a vehicle of the character described, journal-brackets, sleeves attached to the said journal-brackets, hearings in the frame of the said vehicle to receive the said sleeves, drums jonrnaled in the said journal-brackets, and having spiral flanges thereon, a transverse shaftjournaled in the said sleeves in the journal-brackets and geared to the said drums, and means for turning the said shaft, substantially as described.

2. In a vehicle of the character described,- the combination with journal brackets; sleeves on the said jonrn al-brackets; journalbearings in axial line with the said sleeves; a pair of journal-bearings at right angles to the said sleeves; shafts journaled in thelast mentioned journal-hearings; and drums having spiral flanges thereon mounted upon the said shafts; of hearings in the frame of the vehicle to receive the said sleeves; a transverse shaft journaled in the said sleeves and geared to the aforesaid shafts; and means for turning the said transverse shaft; substantially as described.

In testimony whereof We affiX our signatures in presence of two Witnesses.
